视频播放MPMoviePlayerViewController

https://github.com/potato512/SYAVPlayer

使用MPMoviePlayerViewController进行视频播放

注意：

1、iOS9版本及以上版本已经弃用网络视频的播放了，所以MPMoviePlayerViewController现在大部分只是用作本地视频的播放，当然也并不是完全不能播放网络视频。

2、要想实现既能播放本地视频，又能播放网络视频，同时又能根据需求定制播放界面，可以采用其他的播放framework（如AVFoundation中的AVPlayer）。

3、在使用网络视频地址，或本地视频地址时，注意NSURL的使用方法：

（3-1）网络视频地址（URLWithString）：

NSURL *networkUrl = [NSURL URLWithString:@"xxxxxx"];

（3-2）本地视频地址（fileURLWithPath）：

NSURL *localUrl = [NSURL fileURLWithPath:@"xxxxxx"];

// 导入头文件
#import <MediaPlayer/MediaPlayer.h>

@property (nonatomic, strong) MPMoviePlayerViewController *moviePlayerController;

- (void)movieNotification
{
// 添加通知中心
[[NSNotificationCenter defaultCenter] addObserver:self
selector: @selector(moviePlayingDone)
name:MPMoviePlayerPlaybackDidFinishNotification
object:nil];
}

// 播放事件
- (void)moviePlayingDone
{
NSLog(@"播放完成");
// 方法1
// [self.moviePlayerController.view removeFromSuperview];
// 方法2
[self.moviePlayerController.moviePlayer stop];
[self dismissMoviePlayerViewControllerAnimated];

self.moviePlayerController = nil;
}

- (void)moviePlay:(NSString *)filePath
{
// 方法1
if (filePath)
{
NSURL *movieUrl = [NSURL fileURLWithPath:filePath];

if (movieUrl)
{
self.moviePlayerController = [[MPMoviePlayerViewController alloc] initWithContentURL:movieUrl];

MPMoviePlayerController *moviePlayer = [self.moviePlayerController moviePlayer];
moviePlayer.movieSourceType = MPMovieSourceTypeFile;
// 控制播放行为
moviePlayer.controlStyle = MPMovieControlStyleFullscreen;
// 控制影片的尺寸
moviePlayer.scalingMode = MPMovieScalingModeAspectFit;
// 准备播放
[moviePlayer prepareToPlay];
// 播放
[moviePlayer play];

// 在当前view上添加视频的视图
// 方法1
// [[[UIApplication sharedApplication] keyWindow] addSubview:moviePlayerView.view];
// 方法2
[self presentMoviePlayerViewControllerAnimated:self.moviePlayerController];
}
}
}

// 按钮播放事件
- (void)startPlay:(UIBarButtonItem *)button
{
// 获取不到视频文件路径？？（添加方法不当。因复制粘贴到项目文件夹，然后再添加文件到项目）
NSString *moviePath = [[NSBundle mainBundle] pathForResource:@"movie" ofType:@"3gp"];

[self moviePlay:moviePath];
}
